I just started to get a grip on C++ and and went through the tutorial.
However, not even the standard "hello world" exercise works out :( I
do get a linker error "[Linker Error] Unresolved external 'WinMain'
referenced from C:\PROGRAM FILES\BORLAND\CBUILDER5\LIB\C0W32.OBJ"
my code (Borland C++ builder 5) is as follows:
#include <condefs.h>
#include <iostream.h>
#include <conio.h>
#pragma hdrstop
//---------------------------------------------------------------------------
int main (int argc, char **argv)
{
cout << "Hello World!" << endl;
cout << endl << "press any key to continue...";
getch();
return 0;

Any idea?
Unfortunately, yes. You're building this as a Windows application.
You mean a Windows GUI subsystem application.
If so, then your application doesn't start in 'main', it has to start
in 'WinMain',
That's a common misconception. Both Visual C++ and g++ supports
standard "main" for GUI subsystem application, and I haven't heard of
any compiler that doesn't. g++ supports standard "main" by default,
Visual C++ supports standard "main" when using appropriate switches (by
default Visual C++ is also non-standard-conforming wrt. exceptions, RTTI
and for-loop syntax, so it must be browbeaten into submission).
which you don't have and that's what the linker is
complaining about. MS Windows programming is not the same as just
plain programming. That's why you probably want to set aside the
"Windows" side of things for now and switch to creating what is known
as "Console Applications".
Good advice.
I'd add: use command line tools for building.
An IDE adds too much "helpful" stuff that just gets in the way.
See appropriate settings described in the
help system for your compiler. Or ask in the newsgroup dedicated to
your compiler (see the 'borland.public.*' hierarchy).
Yeah.
